The CRG mirrors are the finest bar-end items you can buy. Get some now. Or just get one..depending on how narrow/minimal/blind you like to be. Let cost be no object 'You ride a Ducati, right?' I hate that excuse..but if a mirror is worth $80, this one is. I got mine from
http://ca-cycleworks.com - even though they're mfg'd down the road from me...
The CRGs are very very high quality stuff. I derive far more enjoyment from this mirror than I should.
I used to have those $5 mtn bike bar enders too..quite the bang for your buck - but I got tired of constantly moving them back into position after an 8hr road trip..My gf is still ribbing me about that... 'who's back there? oh wait, gotta adjust the mirror'
Also, didnt feel bad about thwacking the cheap ones on..things..while passing..but you shouldnt do that anyway. And they scratch.
Used to use Napoleons on my Guzzi, and they were great for $15, but still a little wide (not that it mattered with a Goose), and the CRGs didnt exist yet...
